I am running version 2011.2.712.40 which I think is the latest version. When my project loads the first time I get the following error:

Microsoft JScript runtime error: Unable to get value of the property 'tHead': object is null or undefined

The highlighted code is in the RadTreeList prototype.

Telerik.Web.UI.RadTreeList.prototype=

...

_getTableHeaderRow:function(b){var c=null;

if(b.tHead){for(var a=0;

a<b.tHead.rows.length;

a++){if(b.tHead.rows[a]!=null){if(b.tHead.rows[a].cells[0]!=null){if(b.tHead.rows[a].cells[0].tagName!=null){if(b.tHead.rows[a].cells[0].tagName.toLowerCase()=="th"){c=b.tHead.rows[a];

break;

}}}}}}return c;

},

...

The declaration of the RadTreeList looks like this:

<telerik:RadTreeList ID="myData" runat="server" DataSourceID="sqlData" DataKeyNames="ID" ParentDataKeyNames="ParentID" AutoGenerateColumns="false" OnDataBound="myData_DataBound">

<Columns>

...

</Columns>

<NoRecordsTemplate>

<span>There is no data selected!</span>

</NoRecordsTemplate>

</telerik:RadTreeList>

Is there something I am missing that would cause this error as it does not happen on version 2011.1.519.40?

Dynamically Create Notification

I am trying to dynamically create a Notification in code behind, however when I call the Show() method, it gives me an Object is not set to the instance of an object error.

I am assuming that is because this control must be added to the page's controls?

Is that the case?

I have a large project with many pages and controls and don't want to have to add the markup on every since page of my project.

Error when renaming a folder

Hi

I am trying to implement some validation on new folder name so that when a user changes a folder name to another name, he/she does not enter an invalid char in the new name.

When doing so, I tried to rename a folder from (name) to (name/), i.e I inserted a forward slash at the end of the folder name.

When presseing enter, the application timed out and my (RadFileExplorer1_ItemCommand) event never got triggered.

I also found another issue:

If I put the slash in the middle of the new folder name (i.e. na/me), in the RadFileExplorerEventArgs, and newpath parameter will be wrong!

I suggest that there should be internal validation on invalid characters both in file and folder names. Also, the newpath parameter should contain the new name of the folder rather than the whole path, so that if the developer did his/her own validation he can easily find the new name. This is particularly useful if the user entered a slash in the new folder name then If I parsed the full name I still get errors.

I hope my points are clear

Regards

problem with radopen

I have a menu on a master page that opens a radwindow (window1) this window contains a radgrid. In the radgrid I have some code that opens a second window (window2) to allow editing of the grid contents. This works ok, but Im having a problem referencing window2 if my .aspx page is in a subdirectory and not the site root. Heres whats happening

I activate window2 when my main page is

/Website/default.aspx the page is in the root (using this bit of code var oBrowserWnd = GetRadWindow().BrowserWindow;)

I call this code

var oBrowserWnd = GetRadWindow().BrowserWindow;

oBrowserWnd.radopen("ArtistAdmin/BandMemberEditForm.aspx?ID=" + id, "BandMemberDialog");

return false;

the edit form is found and opens ok

If the .aspx page happens to be in a subdirectory, eg

/Website/ArtistAdmin/ArtistAdminPage.aspx

the window cant be found because BrowserWindow is
/website/artistadmin/artistadmin.aspx

so radopen tries this

/website/artistadmin/artistadmin/artistadmin.aspx

How can I force radopen to use the root directory of my site ?

[Solved] On initially loads up, the lists are shrunk down and cramed into the side, then after the page finishes loading they expand to fill.

Hello,

I have used a RadSplitter with two RadPanes inside it. One RadPane have a RadTreeView and second one have RadGrid.

On the initial load of the Page both the panes are shrunk down and cramed into the left side of the Page, after completion of the page load they are expanded.

This problem occurs in the Internet Explorer, while in Firefox and Chrome it works fine.

I have attached images.
1) Problem Image : This is the Problem.
2) Actual Image : This is the actual Image which shows the real output.

Please provide me any solution to this problem.

Thanks in advance.

Does radconfirm support themes?

When I bring up a radwindow, like below, it uses the currently set theme.

function ShowImport(sender, args) {

var radWindow = $find("<%=ImportWindow.ClientID%>");

radWindow.show();

}

However, when I bring up a radconfirm, it doesn't use the theme and instead uses the default theme.

function DeleteTemplate(sender, args) {

radconfirm("Do you really want to delete the selected template?", onDeleteTemplate, 300, 100, sender, "Are you sure?");

}

Any idea what gives?

Thanks,
Jamie

RadEditor Height in Millimeters

When i set the height and width of the radeditor in millimeters the height of the content area in the radeditor is wrong.
What is does is set the height of the Top editor div in px instead of millimeters the min-height is correctly in millimeters.
This problem only occurs in IE8 (the only IE i tested) i also tested it in Firefox4 and there it worked correctly.
